The church of Roupy was rebuilt in 1922, at the same time as all the municipal buildings according to the plans of Jean Charavel. The bell tower, porch and spire of the church are made of concrete lace. Inside there is a magnificent Way of the Cross painted by Paul Charavel on maroon canvas. The nave is lit by six stained glass windows in Art Deco style. The rose window and stained glass windows have just been completely restored as well as the entire building. The church will be open to Heritage Days. One free will close these days on Sunday at 4 pm.
